Casual gamers need never look far to find a Hidden Object based treat on the App Store. It's one of the most plentiful of genres with each title involving a series of puzzles and a variety of different scenes to explore. Because there's so much choice, this seemed like the perfect time for us to round up our four favorite titles and explain just why they're so great.

Time Trap HdOTime Trap is a particularly distinctive title thanks to its beautiful if surreal landscapes. Deviating away from more conventional Hidden Object settings, the game sticks with a Sci-Fi post apocalyptic style theme for its suitably long story. Its moodiness juxtaposes with its hidden object ways but that makes it stand out all the more. It gains extra value through its spooky soundtrack.

Little Things ForeverLittle Things Forever is the antithesis of Time Trap. It's immensely colorful and cheery. There's no storyline to follow with the focus entirely on solving Hidden Object based puzzles, but there's plenty of fun within. Players find objects within intricate pieces of artwork, simply for the joy of doing so. The game's lists are randomly generated, also, so there's limitless fun to be had.

Midnight Mysteries: Devil On The MississippiThe Midnight Mysteries series is great for combining Hidden Object elements with adventure gaming tropes. Devil On The Mississippi offers precisely that. There's a spooky story to be told but alongside that are plenty of puzzles to be solved and objects to be found. In each case, such interactive elements are some of the finest you can discover within the genre.

Strange Cases: The Lighthouse MysteryWhat stands out most about this title is the variety of types of objects to be found. It's a fairly typical but enjoyable title from Hidden Object experts, Big Fish Games, but it keeps things interesting. Some scenes offer a standard list of objects to find while some offer merely the silhouette or clues to what needs finding. It'll keep players on their toes but happy.
